The Classification Of Commonly Used Water-Based Paint Additives

Water-based pressure sensitive adhesive   Typical varieties are: transparent sealing tape, electrical insulation tape, masking tape, surface protection tape, double-sided tape, metal foil tape, pipe anti-corrosion tape, logo tape (printing tape), silicone heat- Conductive tape, shock absorptive tape, medical tape, transfer tape, adhesive labels, stationery adhesive films, advertising adhesive films, notes stickers and medical adhesive tablets, and so on. The application of water-based pressure-sensitive adhesive products according to the needs of sticky objects and bonding environment and the needs of bonding performance to choose a variety of suitable applications of pressure-sensitive adhesive products. Now lists a variety of water-based pressure-sensitive adhesive products application and selection table.

The internal structure of the aqueous   acrylic emulsion   particles will have an impact on several aspects of the water-based paint formulation. the phase structure will first affect the choice and addition of film forming auxiliaries.Different phases have different hydrophilic / lipophilic characteristics,the lipophilicity of film forming additives is also different.For example, two propylene glycol methyl ether (DPM) is higher hydrophilicity, lower lipophilicity than two propylene glycol butyl ether (DPnB).If the outer layer of the aqueous acrylic emulsion particles is a highly lipophilic phase, the addition of DPM not only affects the film formation, but also allows the excess DPM in water to affect the other properties of the water-based paint film. The other effect of phase structure on the formulation of aqueous coatings is the effect on the film quality of water-based paint film.The key to the quality of the film is in the mixing process of the aqueous acrylic emulsi...

In the formulation of water-based coatings, the selection of raw materials is the most important decision.The main performance of the coating is determined by resin. Water-based acrylate emulsion ,including polystyrene acrylate emulsion,a great variety and market jumbly. Different water-based acrylic resin composition have a great impact on the film-forming and cost of water-based coatings. 1. Principal raw material A. Styrene:The primary reason for the introduction of the monomer into the polyacrylate emulsion is that it provides a high glass transition temperature (Tg),So as to improve the hardness of the film;The other reason is cost.The amount of Styrene in the packaging industry is large,is one of the most important downstream products in the oil industry,low price but vulnerable to macroeconomic.However,the introduction of styrene, in particular, its content is higher than the total monomer volume of more than 15%,will bring a lot of negative effects to water-based paint f...

Anhui Sinograce Chemical Co., Ltd. participated in the twenty-third China International composite materials industry technology exhibition in from September 6th to 8th.  At the exhibition, we mainly display   glass fiber positioning adhesive ,   self viscose   and other hot products. Before the exhibition, we made an appointment with the Indonesian customers in advance. At the exhibition, we carried out a deep discussion on   water-based glue ,   water-borne polyurethane wood paint ,   metal paint   and   special resin for labor protection gloves . In addition, several other customers at the exhibition have also taken a great interest in our products, and two customers went straight to the factory and expressed satisfaction with our production line and service.  Anhui Sinograce chemical's products by the vast number of new and old customers. Many customers on-site detailed consultation, hope that through this opportunity to carry...

The rubber pressure-sensitive adhesive in addition to the main components of rubber, while adding a thickening resin, plasticizers and so on.  The rubber type pressure-sensitive adhesive is made of rubber elastomer, thickener, softener, antioxidant and other components dissolved in the preparation of solvent. In addition to resin, resin pressure-sensitive adhesive must also add to defoamer. Wetting agents and so on.  Among the resins,  polyacrylate   is currently the most widely used, it is generally used for sealing   tape ,   labels , stickers and women's products. Silicone and other resin-based pressure-sensitive adhesive are composed of silicone resin and silicone rubber mixture of pressure-sensitive adhesive, with high temperature and anti-aging properties, is a very important special pressure-sensitive adhesive.

How to judge the quality of waterborne pressure sensitive adhesive？ Pressure-sensitive adhesive   quality of good or bad, generally from the drying speed, viscosity, adhesive strength, solid content and PH value and other aspects to measure. 1, pressure-sensitive adhesive drying speed When buying pressure-sensitive adhesive, it is necessary to measure whether the drying speed matches the bonding process. The general manual bonding process is slow, requires a long initial dry time; Machine bonding process is very fast, requiring short initial drying time. For the initial dry time, the vast majority of cases require the sooner the better, so as soon as possible into the next road process. 2, the viscosity of pressure-sensitive adhesive Viscosity is the most important factor affecting the quality of adhesives. If the viscosity is too large, the coating is thick, consumption of plastic large, slow drying, but also affect the adhesive on the surface of the sticky material we...

China's   adhesive   industry in recent years has made relatively large progress, the specific performance are in the following areas: (1) New products continue to emerge. Some modified type, knot type, copolymer blending type and special type of adhesive have been developed, some have realized the industrialization. Such as polyurethane modified polyvinyl acetate emulsion, frost-resistant white latex, double-horse modified epoxy conductive adhesive, silicone modified epoxy resin and so on. These products have a lot of excellent performance, not only to meet the various needs, but also improve the grade of China's adhesive products, replacing some of the imports. (2) Production technology to accelerate. China's adhesive production technology has made great progress. The new production technology represented by radiation, UV solidification and interpenetration network, In improving product performance, improve the quality of products, has played a very important role in impr...
